I've seen a couple people around her mention it, just curious how many people use it, and how often. I'm contemplating getting a few bettas, but want to know what it's like first. How do they ship the fish? I'm sure it's safe, but I'm warry. Also for the most part, what are your experiences with AB? good/bad/indifferent

I don't buy fish from Aquabid, but I do love looking at all the gorgeous bettas they have there. Couple things you may want to bear in mind though - find out where the seller is located. If it's anywhere outside of your country (aka outside of the US) you will have to pay trans-shipper fees, as well as shipping fees in the states, because the fish must go through customs inspections at the border, and only so many people can do that.
If you get a breeder that is located in the US, then you simply need to be pay for shipping, but know that can sometimes add up to be pretty expensive depending upon how far away you live from the breeder. It can be an expensive endeavor, but if you really want a well-bred betta, then I suppose that is one way to do it.

I have had nothing but good experiences purchasing on Aquabid........There are fish on there that i cant find locally and its nice to find something rather odd or rare...........If you do your homework, there are some sellers who have free shipping on there fish..........My shipped fish have come in an insulated box with a heatpack and newspaper for added insulation..........everyone arrived alive!!.................I, myself havent purhcased anything out of the country though
